In a laser based curing apparatus, the acts both as the curing light and the excitation source for a Raman spectroscopic sensor. The spectroscopic sensor provides real-time, in situ, non-invasive curing status monitoring via Raman spectroscopy. The spectroscopic information can be further used to control the operation parameters of the laser to achieve the optimum cure result.
